Chaetocnema concinna
brassy flea beetle, hop flea beetle, beet flea beetle, brassy-toothed flea beetle
Chaetocnema concinna is a small flea beetle native to Europe and northern Asia that has been introduced to North America, first documented in Canada in the late 1980s. In Europe, it is the most important pest of sugar beet, though its economic impact in North America remains unquantified. The species exhibits broad host plant associations and can function as either a pest or beneficial organism depending on context.
Pegomya betae
Beet Leafminer
Pegomya betae is a leaf-mining fly in the family Anthomyiidae, commonly known as the Beet Leafminer. The species is native to the Palearctic region and has been introduced to North America. Larvae feed internally in leaves of beet plants, creating distinctive mines. It is considered a significant agricultural pest of sugar beet and related crops.
Piesma
ash-grey leaf bugs
Piesma is a genus of small ash-grey leaf bugs in the family Piesmatidae, serving as the type genus of the family. Members are less than 4 mm in length and occur across North America, Europe, Africa, and Asia. The genus is distinguished from the similar genus Parapiesma by a notch in the side margins of the pronotum. Species in this genus are primarily phytophagous and include economically significant pests such as Piesma quadratum, which transmits viral and rickettsia-like pathogens to sugar beet and related crops.
Scrobipalpa
Scrobipalpa is a genus of small moths in the family Gelechiidae, established by Janse in 1951. The genus contains over 100 described species distributed across Africa, Asia, Europe, and introduced populations in North America and Australasia. Several species are economically significant agricultural pests, particularly of sugar beet, quinoa, tobacco, and eggplant. The genus was historically split with Euscrobipalpa treated as a subgenus or separate genus, but this distinction is no longer recognized as valid.
